ROOF FLASHING ASSEMBLY Filed June 2, 1958 2 Sheets-Sheet 2 35 INVENTOR. HAR LAN H. EDWARDS Attorneys United States Patent 3,090,161 ROOF FLASHING ASSEMBLY Harian H. Edwards, 900 University St., Seattle, Wash. Filed June 2, 1958, Ser. No. 739,170 1 Claim. (Cl. 5045) The present invention relates to a roof flashing assembly which not only serves as the counter-flashing for bituminous roofing but also serves as a continuous support for the flashing portion of the roofing.

Among the objects of the invention are to provide a flashing construction which is sure, which will self-adjust to shrinkage, settlement or other roof movement, which is readily applicable to a variety of types of building construction, and which is economical and simple to install.

More particular objects and advantages will appear in the course of the following description and claim, the invention consisting in the novel construction and in the adaptation and combination of parts hereinafter described and claimed.

In the accompanying drawings:

FIGURE 1 is a transverse vertical sectional view through an embodiment of my roof flashing assembly installed in a parapet wall of concrete block construction.

FIG. 2 is a front elevational view of the embodiment shown in FIG. 1, with parts broken away.

FIG. 3 is a detail plan view of a lower end portion of the cant member.

FIGS. 4 and 5 are views taken in the same manner as FIG. 1 and showing second and third embodiments installed in parapet walls of brick veneer construction and stucco faced construction, respectively.

FIG. 6 is still a further view taken in the same manner as FIG. 1 and showing a fourth embodiment in which the reglet also comprises a parapet wall facing; and

FIG. 7 is a perspective detail view of part of the facing construction of FIG. 6.

Referring to the illustrated embodiments of my invention, it is seen that each includes a cant member 20 and a counter-flashing 30, the modifications being in a reglet, denoted generally as 40 with letter suflixes applied to the various species thereof. The variety of reglets is provided to enable ready anchoring and waterproofing thereof in dilferent types of parapet wall construction.

For example, for a wall which is brick or is formed of concrete blocks 50 as in FIG. 1, the reglet 40a has a horizontal anchoring flange 41 and up-turned locking lip 42 to be bedded in one of the mortar joints 51. In addition to its anchoring function the flange 41 may extend beneath the core holes of the blocks to intercept any water leaking down therethrough. From the flange 41 the reglet slopes gently downward by an inner apron section 43 as it projects from the wall and then depends as an outer apron section 44. The bottom of the latter has an up-turned terminal hem 45 spaced inwardly toward the wall therefrom. This hem is common to all of my reglet embodiments. It will be appreciated that if the parapet is concrete rather than brick or concrete block, the reglet can be placed in the forms before the wall is poured so that the anchoring flange 41 and the locking lip 42 are concreted in place.

Continuing to the cant member 20 common to all of the embodiments, such may be formed from light gauge sheet metal and has an upper outwardly extending stop flange 21 which mates with the inner apron section 42 of the reglet. From this stop flange the cant member hugs the wall for about four inches below the reglet, suflicient to permit easy hammering of nails 60 through the cant member into the wall. Then the cant member laterally arches as a cove bridging the juncture of the wall and roof deck 64. As shown in FIG. 2, adjoining counter-fiashing extends toward cant members are lapped at their meeting ends except for their stop flanges 21 which are cut away for the length of the lap so as to butt.

It will be noted that the lower longitudinal margin of the cant member is provided with a series of elongated slots 22 for receiving nails 61 driven into the deck. These slots 22 permit the deck to settle or otherwise move relative to the wall while the heads of the nails 61 continue to bear against the upper face of the cant member. More specifically, if the roof deck settles, the nails 61 can work toward the mouths of the slots 62.

When the cant member 2! is nailed in position the roofing layers can be applied to the deck with its respective marginal portion laid over the cant member as a flashing and brought'up to the stop flange 21. The outline of this flashing is indicated by broken lines 63 in the drawings. It is preferred that the mopping of the roofing layers continue all the way to the stop flange 21.

The counter-flashing 30 is formed along its top longitudinal edge with a down-turned hem 31 for interfitting with the hem 45 of the reglet. From this hem 31 the the cant member to bear then has a vertical section 32 from which it continues by outwardly and inwardly sloping V forming sections 33, 34, respectively. The latter section may deflect outwardly at the bottom by a basal lip 35 to preclude puncturing of the roofing hy the lower longitudinal marginal edge of the counter-flashing. Installation of the counter-flashing is readily accomplished by commencing engagement of its upper hem 31 over the reglet hem 45 with the counter-flashing held at about forty-five degrees from the wall and then springing it into the place so that the basal lip 35 bears against the flashing portion of the roofing. In this regard it is preferred to have the section 34 slope inwardly toward the wall slightly beyond the plane of the inner face of the vertical section 32 so that the basal lip 35 will he constantly spring-urged against the roofing. It is preferred to stagger the joints between counter-flashings 3G with respect to the joints between reglets so that the counterflasing serves to key the reglets together in alinement.

For brick veneer construction, as shown in FIG. 4, a modified reglet 40b may be used in which a wider anchoring flange 46 is provided and the locking slip 42 is replaced by a nailing strip 47. With this structure the flange 46 is laid on one of the brick courses and the nailing strip 47 secured against the sheathing 71 or studs as by nails 72. The brick wall is then continued on up beyond the reglet.

Reglet 400 is used when the parapet wall is to be faced with stucco or siding, stucco being shown in FIG. 5 for purposes of example. In this embodiment the horizontal anchoring flanges of the reglets 40a, 40b are replaced by a nailing flange 48 which extends vertically upward from the inner apron section 43. With this arrangement the latter serves as a ground for the stucco mortar which can be dressed out to the apron section 44. For ease of job application the inner apron section 43 can be spot-welded or otherwise secured to the stop flange 21 of the cant member 20 during shop fabrication.

As still another embodiment of my invention, in FIG. 6 I have illustrated a reglet 40d in which the apron section 44 of the afore-described embodiments extends upwardly from the hem 45 as a facing 44d for a concrete parapet wall. This facing is provided at the top with a hem 49 to make a lock seam with a hem turned in from the inside lip 91 of a shop-fabricated parapet cap 92. At its outside edge the cap has a somewhat wider lip 93 serving as a facia for outside building trim. The ends of the facing 44d are hemmed to interfit by lock seams 98.

against the roofing,

On their back faces the facing 44d and cap 92 are provided with metal mesh 94 to be embedded in mortar. The mesh 94 is preferably a self-furring type, the illustrated mesh having a network of crossed rods 9S96 which are furred by offsets 97 bent in the rods 96. These ofisets are welded or soldered to the back faces of the concerned member to secure the mesh in place. The entire assembly of cant member, reglet-facing and cap can be made a part of the forms for the concrete parapet wall so that the mesh 94 is embedded when the Wall is poured. Otherwise, the mesh of both the reglet and cap 92 are embedded in a supplemental coating of mortar 99 applied after the forms have been stripped from the wall.

It is particularly desirable, when the reglet 40d is to comprise part of the parapet wall forms, to provide the cant member with an upstanding lap flange 22 at the outer edge of its stop flange 21. This lap flange is spot welded to the back face of the facing 44d before erection so that it can also be installed as part of the forms.

In the cases of sloping decks, crickets and the like, the cant member 20 normally has its stop flange 21 bent on the job after the upper edge of the member has been trimmed to a horizontal with the bottom of the member in position. Corners and interior angles are prefabricated as needed, allowing for proper laps. I intend that the reglets 40ac may be anchored in walls which extend between difierent roof levels as well as in a parapet wall. It is thought that the invention will have been clearly understood from the foregoing detailed description. Changes will suggest themselves and may be resorted to, without departing from the spirit of the invention, wherefore it is my intention that no limitations be implied and that the hereto annexed claim be given a scope fully commensurate with the broadest interpretation to which the employed language admits. The term cove as herein used is to be given its ordinary architectural meaning of a member whose section is a concave curve.

What I claim is:

In a flashing assembly, a cant member of sheet material secured as a cove at the juncture of a parapet wall and roof deck and terminating at its upper side by an outwardly directed stop flange, the margin of the roofing for said deck laying as a flashing over said cant member up to said stop flange, a reglet anchored to said wall and providing an apron first engaging said stop flange and then depending to terminate at its lower side by an inturned hem, and a counter-flashing member having an upper out-turned hem detachably interfitting with said inturned hem, the depending portion of the reglet having a vertical length at least as long as the combined heights of the in-turned and the out-turned hems so that the counter-flashing member can be detachably interfitted with the installed reglet, and depending therefrom to overlap said flashing.
